1. Your article on nuclear energy just says that France has reactors that need maintenance. It also says they produce less electricity because they need cold water which is not currently available because of heat waves and droughts. Both are temporary problems that can be planned around or avoided by over-provisioning capacity. As the original article notes, you cannot over-provision capacity with renewable energies because they tend to produce 100x less power on windless or cloudy days. 2. It's more efficient to burn gas and collect the heat for industrial processes that go through an intermediary step of converting heat into electricity. I don't think it has anything to do with gas being irreplaceable as a source of heat. Gas can be necessary as a chemical precursor in some reactions - which can't be replaced by electricity - but that has nothing to do with heat.
